APPARATUS FOR TREATING COAL AND ORES.

SPECIFICATION forming part of Letters Patent No. 656,893, dated August 28, 1900.

Application filed May 20, 1899. Serial No. 717,637. (No modal.)

TooZZ whom it may concern:

Be it known that I, J EANNOT W. KENE van, a citizen of the United States of America, residing at Chicago, in the county of Cook, in the State of Illinois, have'invented certain new and useful Improvements in Apparatus for Treating Coal and Ores, of which the following is a description.

Referring to the accompanying. drawings, wherein like reference-letters indicate like or corresponding parts, Figure 1 is a partial front elevation of my improved apparatus. Fig. 2 is longitudinal vertical section in line 2 2 of Figs. 1 and 4. Fig.3 is a transverse vertical section in line 3 3 of Fig. 2. Fig. 4 is a horizontal section in line 4 4 of Fig. 3. Fig. 5is a transverse vertical section in line 5 5 of Fig. 2. Fig. 6 is a similar section in line 6 6 of Fig. 2. Fig. '71s a partial top plan. Fig. 8 is an end view of the apparatus, showing the gas receiver and connection. Fig. 9 is a sectional view showing one way of arranging the gas pipes and burners. Fig. 10 is a section in line 10 10 of Fig. 9. Fig. 11 is a similar section in line 11 11 of Fig 9, and Fig. 12 is section inline 12 12 of Fig. 8.

The object of my invention is to produce an effective and economical apparatus for the treatment of coal and ores and for the elimination of sulfur, phosphorus, or other metalloids therefrom.

To this end it consists in the novel construction and combination of the apparatus shown and described,and particularly pointed out in the claims.

In the drawings, A A, Fig. 2, represent retorts into which coal or ores may be charged through openings ao,which are provided with sealing caps or covers a a.

B B are combustion-chambers.arranged to permit the products of combustion to escape through fines b b to heat the retorts A, Figs. 2, 3, and 4. As will be seen, the fines b 1), Figs. 2 and 3, are provided with return-bends b b, Fig. 2, which aid in heating the retorts and deliver the products of combustion to the superheating-fiuesO, Fig. 4, and thence to the flue P, leading. to a stack D.

Each retort A is provided with means for forcing steam, air, or other gases through the charge. The pipes E serve this purpose, and to facilitate this action in a thorough man 0f the products of combustion from the chambers B through the fines b b will thus primarily heat the retorts A, and in passing through the fines C also superheat the steam,

air, or gases passing through the pipes F, in which condition I prefer to inject it into the charge.

G is a hydraulic main of well-known con- .struction connected to the retorts A by the pipes H. If preferred, a plurality of such mains may be employed, but by suitably positioning the main, as shown, one is usually sufficient. Other pipes I connect the discharge-ports I of the retorts A with one or more suitable discharge-pipes K, by means of which the gases from the retorts may be permitted to escape without passing through the main G. Suitable valves h kcontrol the flow through the pipes and direct the dis charge of the gases and volatile elements through the main G or the pipe K, Fig. 1, as desired.

S, Fig. 1, is an air-fine preferably extendin g transversely across the apparatus and constructed to freely admit the exterior air thereto. For this purpose one or both ends are preferably partially or wholly open.

'3 s are longitudinal fines extending from the flue S parallel to the chambers B and provided with ports 8 s, leading into the combustion-chambers, Figs. 2, 3, 5, and 6.

This construction admits atmospheric air to the chamber B to insure perfect combustion.

The several fines may be and preferably are so positioned as to heat the inflowing air to a marked extent, which is a decided advantage in the rapid treatment of the charge.

L L are receptacles for containinga liquid which it is desired to deliver into or through the charge with the current of steam, air, or other gases at or during some stage of its treatment. For this purpose the tanks or receptacles L are so arranged that when dosired the contents may be regularly delivered under the control of suitable valves Z into the steam or gas pipes E at some point between the source of supply of the steam or gas and the point of delivery with the charge at the jets 6. By this means the liquid becomes thoroughly vaporized and incorporated with the passing steam or gas, and is thus uniformly and evenly distributedthrough the charge. The liquid I have preferably employed has been an acid solvent of sulfur or phosphorus, and by injecting said solvent, as described, at the proper time I am enabled to free the resulting product of a larger per centage of those undesirable metalloids than is possible by the means usually employed. The overflow from the main G may pass off by the pipe M.

M is a pipe connecting the bottom of the main with the overflow-pipe M, whereby the main may be drained when desired. A valve described is as follows: The retorts A are.

charged with coal or ores, and all openings being closed the fires are then started in the combustion-chambers B. The products of combustion passing along the sides of the re torts through the lines I) b primarily heat the retort, thence passing through the fines O superheat the steam, air, or other gases in the pipes F, thence passing into the flue P, finally escaping by means of the stack D. The rising temperature in the retorts causes the release of the gases and volatile elements from the charge. The chemical action attending therelease of the said gases and elements has the effect of increasing the temperature, accelerating the process. The escaping gases and volatile elements pass through the pipes H into the main G, where the by-products may be secured in the manner now well known. The gases are thus washed and may then be conducted by the pipe 0 to the receiver O for use or be permitted to escape, as preferred. After the richer part of the gases and volatile elements have been thus secured and the temperature raised to a suitable point (preferably from 1,500 to 2,100 Fahrenheit) the valve h is closed and the valve opened. The steam, air, or other gases is then turned on and escapes through the pipes E and jets e e into the charge, and being under suitable pressure for the purpose forces its way through the charge, carrying the released metalloids therewith out through the port I and the pipe K. To facilitate the more perfect-elimination of metalloids, such as sulfurand phosphorus, I prefer to inject into the passing steam, air, or other gases an acid solvent of those substances, as, stated. I prefer to use acetic acid for this purpose, and find that when in the form of good commercial vinegar it is adapted for such use. The acid solvent is placed in the receptacle L and is delivered from thence into the pipes E as desired. The exact procedure here described need not necessarily be followed, though preferred as stated. Thus in some cases I prefer to discharge the steam or its equivalent into the charge at intervals, say, of five minutes each during the operation or at intervals during only a part of the operation. In some cases it may be desirable to reverse the steps as to passing the escaping gases and elements out by means of the escape-ports Z and pipe K or main G, and such changes are contemplated by me in treating coals or ores varying in quantity. When the treatment is completed, the charge is removed in any suitable manner. This may be done through the doors A A.

When the gases are stored in the receiver 0, as desired, they may be used for all the usual purposes, including the heating of the retorts A. Figs. 8, 9, 10, 11, and 12 show two ways in which this may be accomplished. In that shown in Figs. 8 and 12 the pipe 1 conducts the gas along the ends of the retorts, supplying gas to the burners in the combustion-chambers B. The air-pipe 3 supplies the necessary oxygen or atmospheric air to secure perfect combustion. Valves 4 control the burners. In the preferred form shown in Figs. 9, 10, and 11 the gas supply-pipe 1 is located in the flue S, with branches 5. extending into the fines s to supply the burners 6, which are so located in the ports 5 as to permit sufficient air to be admitted to secure perfect combustion. This method has a distinct advantage in the fact that the combustion is secured at a plurality of points along the sides of the chamber B and are forced inward, insuring a very perfect and equableheating of the retorts. When the latter method is employed, the grate B may be, if desired, removed or be changed to a position where it will not interfere with the. operation of the burners 6.

I11 using the word steam in the following claims I intend to be understood to include also air or other gases as above stated.
